Ad Age Datacenter contains current information about advertising spend for top brands. It also has Advertising Age's Agency Report, an annual ranking and analysis of advertising and marketing-services agencies. The report includes rankings based on U.S. and worldwide revenue. The Agency Report appears in Ad Age's print edition and in expanded form on AdAge.com. The online version includes Agency Family Trees, a database showing fast facts, executives, links and more content related to holdings of the world's 50 largest agency companies. Ad Age has published Agency Report every year since 1945.

Business Source Premier and Communication & Mass Media Complete are library databases containing full text articles on many advertising and marketing topics. Be flexible and creative with your search terms. Check the subjects listed in some of your best search results to get a sense of how articles on your topic are indexed in the database. Statista is another good source for company and brand information.
Because they are both hosted by Ebsco, you can search both of these databases at the same time - see the screenshots below to guide you through that search process.
